PbRTABLE INCINERATOR.

Application filed thine 21, 1828. Serial No. 117,349.

The object of this invention is to provide an improved portable device adapted for the reception of waste matter such as garbage. and to dispose of such waste matter by dehydration and combustion.

A further object of this invention is to provide, in a portable incinerator, improved means for receiving and imparting a delayed traveling motion to waste products and at the same time subjecting such products to the influence of heat, whereby at the end of the travel the products may be deposited in a fire box and successfully consumed.

A further object of the invention is to provide improved means for feeding waste products to a fire box after subjecting them for a considerable period to the drying influence of heat.

With these and other objects in view, my invention consists in the construction, arrangement and combination of elements claim and illustrated by the accompanying drawing, in which- Figure 1 is a plan view of a portion of my improved portable incinerator.

igure 2 is a side elevation of the same. igure 3 is a longitudinal section on the 33 of T igure 1.

rigures l and 5 are cross-sect ons on the lines 4-et and 55 respectively of Figure 3.

The device comprises a housing or box 10 formed of s teet metal such as boiler sheets suitabl v reinforced and mounted on trucks 11. provided with a pole 12 or otherwise suitably arranged to be drawn along the streets. The housing 10 is enclosed on all sides, but preferably there is a large opening '21 its top closed by a hinged door 13. Across one end of the housing 10 is a hopper and a platform 15. with steps 16, is arnng t below said hopper. The opposite portion of the housing is formed as a box 17 having a grate 18 beneath which is an ash pan 19. A door 20 in one side of the housing is formed integral with the ash pan 19, and a door 21 in the end of the housing gives access to the fire boX. Any suitable means be provid-ed for producing combustion in the fire box, such as one or more oil or other hydrocarbon burners 22 arranged adjacent the grate 18. The burners 22 may be fed by a pipe 23 leading from a supply tank or mounted in elevated position at one side of the housing, and preferably a blower device 25 also is provided,

longitudinally of the upper portion of the housing 10 are a number of tubular dryers 29, in this instance three in number. The dryers 29 are journaled for rotation in the end walls of the housing or in bearings 30,

and at one end they communicate with and are adapted to receive substance from the hopper let. From their initial ends the dryers 29 incline downwardly somewhat inthe housing and pass through the fire box 17 a above the burners 22, to which they are hereinafter set forth, pointed out in the adapted to discharge their contents through large openings 31 formed in their sides, or any other suitable manner of discharge into the fire box may be provided. At their terminal ends the rotary dryers 29 are provided with suitable gearing 32 outside the housing, by which they are conjunctively rotated, and driving means such as sprocket gearing 33 is provided for driving said dryers from the motor 27, such sprocket gearing in this instance being associated with a transverse shaft 34 at the end of the housing having bevel gear connections 35 with one of the dryers.

i Vaste material such as garbage is dumped into the hopper 14 and enters the rotary d.;yers 29, and as they are slowly rotated the substance travels slowly down the incline toward the fire box and is dried by heat therefrom, products of combustion passing along the housing and in contact with the dryers to a flue 36 on the housing near the hopper. This slow travel dehydrates the substance and thoroughly dries it so that the major portions thereof are combustible and are consumed when deposited upon the burners 22 or the grate 18. As such products usually contain large quantities of carbon, it follows that when thus dried and deposited they will burn readily and in fact will provide considerable available fuel for producing heat to dry quantities of waste material subsequently received in the dryers. After combustion is well established, it will often be found that some or perhaps the major portionof oil or other auxiliary fuel supplied to the fire box may bewithheld and combustion be continued wholly or in large part by the dried waste products deposited bythe dryers.

If desired a cylindrical heater device 87 may be mounted for rotation in the hopper what in their passage 14;, provided with suitable teeth or the like for picking, tearing or otherwise disintegrating themass of waste substance depos- V ited in the hopper, and causing" it to travel toward the mouths of the rotary dryers. The'beater device 3r 1S driven by achaln' or belt 38 from the engine 27.

, A transverse partition 39 preferably is arrai between the fire box- 17 and remain 1. portion of the housing interior and eiztend from the grate up to the dryers t 29, se that heated products of combustion deposited therein as it is collected, and imfrom time to time and otherr se mediatcly consumed. Any portions which are not consumed can of course be removed disposed Of but it is believed the greater portion of all 7 kitchen and household garbage can thus be consumed. It thus saves the cost of lengthy transportation of the substance and of a separate and usually expensive incinerator or rendering plant.

The fire box may be providedwith a heatresisting lining 40 of asbestos or other suitable material.

' The slow rotation of the dryers also serves to agitate the contents, and to prevent undue heating of the material of which they are made.

I claim. as my invention 7 A portable incinerator, comprisinga housing arranged for transportation, a fire box in one end of said housinp', means for producing combustion in said fire box, a hopper at the other end of said housing, a plurality of tubular dryers arranged side by side in the upper portion or" said housing and inclining downwardly from said hopper to the fire her; and provided with discharge means to the latter, the discharge means of each dryer being; staggered. circumterential y relative to the discharge means of adjacentdr er and means forrotating said tubular dryers.
